PROBLEM TO BE SOLVED: To provide ambient temperature cured coated articles where the coating is a rubbery, high elongation, weatherable coating composition as a mixture of two liquid parts, a first part containing a solution of a functional film forming polymer and the other part providing a curing component.SOLUTION: The stability as a first-part premixed solution is limited to up to several months. A curable film former and a curing component are mixed together at a total solid content of 4-25%. The viscosity is less than 20,000 cps (Brookfield) such that the coating can be sprayed, brushed or dipped to form thin coatings of 0.001-0.020 mil. Coated rubber articles containing metal conductive particles exhibit heat emissive properties useful for extending the service life of the articles.
